Vacuum Jar

Post by remlap12 »

Hi all,

What bell does everyone use in their vacuum jars? :unsure:
Last minute prac this morning, of course!
Only had old bells, but we couldn't get it to hang in the jar. The bell sat on the base of the jar, it kind of worked but I need to buy a bell that will hang happily from the lid of the jar.
Appreciate your suggestions..................

Helen

At one school, the teacher would just use one of the electronic timers and set it. It just sat on the base and seemed to work fine. At another school, they had bought a set up where the bell was fitted on a stand that was fitted to the base.

We use a little analogue alarm clock and it works well.
